OSCAR J. SUNDSTBAND, OF ROCKFORD, ILLINOIS, ASSIGNOR TO ROCKFORD MILLING MACHINE COMPANY, OF BOGHOBD, ILLINOIS, A CORPORATION OF ILLINOIS.

CASH REGISTER.

Application med August 15, 1921- Scrial No. 492,243.

To all whom it may concern: I

Be it known that I, OSCAR J. SUNDSTRAND, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Cash Registers, of which the following is a specification.

This invention relates to cash registers of the type consisting of a self-contained adding and listing machine and a cabinet containing a cash drawer, the adding and listing machine-being positioned upon the cabinet or casing and arranged to cause the cash drawer to be unlatched.

The object of the present invention is to provide a simple and efficient operating connection between the adding and listing machine and the cash drawer, and means for properly locating the machine upon the cabinet.

In the accompanying drawings,

Fig. 1 is a side elevation of a cash register embodying the features of this invention, certain parts being broken away. In this view the cash drawer is shown closed and latched. v

Fig. 2 is a fragmental horizontal view taken in the plane of dotted line 22 of Fi 1.

Fig. 3 is a view taken in the plane of line 33 of Fig. 2.

Fig. 4 is a section on line 4.4 of Fig. 2. Fig. 5 is afragmentary detail view.

While the invention may be utilized in connection with adding and listing machines of various types, I have herein illustrated a machine substantially identical with the one disclosed in the Sundstrand Patent No. 1,198,487, dated September 19, 1916. Said machine is provided with a base 40 anda casing 274 which encloses substantially all of the mechanism. The base 40 is supported upon rubber feet a.

The cabinet or casing which contains the cash drawer may partake of any desired form. In the present instance, I have shown a cabinet similar to the one illustrated in Design Patent No. 57 ,742, granted April 26, 1921, to Rockford Milling Machine Co. This cabinet is herein designated C. It comprises a table or platform D upon which the adding and listing-machine may be set. Directly below the platform D is a space containing a cash drawer E.

The means for holding the drawer in the closed position may be of any suitable character. Herein is shown a lever 1 pivoted at 2 in the rear portion of the cabinet C carrying at one end a stud 3 adapted to engage a hook at secured to the rear end of the cash drawer E. The opposite end of the lever 1 carries a projection consisting, in this instance, of a plate 5, the upper edge of which is arranged to be engaged by a latch 6 which is pivotally supported at 7. A coiled contractile spring 8 normally holds the forward end of the latch 6 down behind the upper edge of the plate 5. A coiled expansive sprliln g 9 pressing against the lever 1 norma war y and holds the plate 5 pressed against the latch 6. The rear end of the latch 6 underlies a plunger 10 which is vertically reciprocable in a tubular guide 11 secured to the cabinet C. The guide 11 projects upwardly from the platform D, its upper portion passing through an opening 12 formed in the base 40 of the adding and listing machine. Upward movement of the plunger 10 may be limited in any suitable manner, as, for example, by means of a screw or other projection 14 (Figs. 4 and 5) upon the lower portion of the plunger, said projection being normally held in contact with the portion 11 of the guide 11 by the spring 8. The mechanism of the adding and listing machine comprises a horizontal rod 15 tends to project the cash drawer forwhich moves downwardly whenever the 'actuating handle 27 of the machine is pulled forward by the operator. When the handle 27 is released, the coiled contractile s ring 36 restores the handle to the position s own in Fig. 1 and, movesthe rod 15 upwardly. The rod 15 operates in the rear portion of the casing 274. The plunger 10 is so located as to be in the path of movement of the rod 15. Consequently, when the rod 15 descends, the plunger 10 is depressed.

The downward movement of the plunger 100 causes the latch 6 to tilt "upon its pivot 7 against the tension exerted by the spring 8, whereby the forward end of the latch is disengaged from the plate 5, thus releasing the lever l to the action of the spring 9. 105

The latter thereupon causes the lever l to turn in the direction to push the cash drawer E out of the cabinet C a short distance, the movement of the lever being sufficient to withdraw the stud 3 from the heal: a

so that the operator may pull the drawer still farther out, if desired.

In operation, the clerk registers the amount of the sale by operating the adding and listing machine in the usual manner. When the handle 27 is drawn forward, the rod 15 is moved downwardly into engagement with the plunger 10, whereby the drawer is unlatched. The handle 27 being released, the spring 36 returns the handle 27 and the rod 15 to initial position, as shown in Fi 1. When the operator closes the drawer the lever 1 is caused to swing into engagement with the latch 6, the stud 3 being then within the hook 4 so that the drawer is held in the closed position until the handle 27 is again operated.

It will be noted that the guide 11 serves to locate the adding and listing machine in proper operative relation to the drawerlocking mechanism, which relation is not affected by any slight shifting of the forward portion of'the machine upon the platform D about the guide 11 as a pivot.

- It will also be noted that the plunger. is enclosed within the guide 11 and the casing 274 and thusis not accessible from the outside of the machine, and therefore the cash drawer cannot be opened without operating the handle 27 or removing the adding and listing machine from the cabinet C. It is obvious that the tubular member 11 performs the double function of locating the machine and protecting the member 10 from operation other than by the mechanism of the registering machine.

If desired, suitable means may be provided to operate a bell or gong whenever the cash drawer is opened.

It will be evident the adding and listing machine may be lifted off the platform D A and taken to any point where it may be desirable to use the machine in the performance of computations and the preparation of lists of items, statements of account,

etc.

Attention may be called to the fact that the Sundstrand adding machine may be employed in connection with the cash drawer herein disclosed without the addition of any mechanism to said machine.

I claim as my invention:

1. The combination of a casing, a cash drawer in thecasing, a drawer lock in the plunger projecting above the guide and being arranged to be moved by the'registen ing machine.

2. The combination with a casing having a cash drawer therein, and a latch in said casing for the drawer, of a registering machine having a casing enclosing the mechanism thereof and having a suitably disposed opening in the base, the machine being removably positioned on the first-mentioned casing and over the drawer, the

-mechanism of the registering machine including a movable member located within the rear end of the registering machine casing, a movable member extending from the cash drawer casing up thru the opening in v the base of the registering machine lnto position to be operated by said vertically movable member to release the latch of the drawer, and a tube fixed on the casing and enclosing the last mentioned movable member and cooperating with said openin to properly locate the registering mac ine when it is placed upon the casing.

In testimony w ereof, I have hereunto set my hand.

OSCAR J. SUNDSTRAND.
